1
Temperature range of A and B grades is −40°C to +105°C.
2
Linearity calculated using a reduced code range: AD5665R (Code 512 to Code 65,024), AD5645R (Code 128 to Code 16,256), AD5625R (Code 32 to Code 4064). Output
unloaded.
3
Guaranteed by design and characterization; not production tested.
4
Interface inactive. All DACs active. DAC outputs unloaded.
5
All DACs powered down. Power-down function is not available on 14-lead TSSOP parts when the part is powered with V
DD
< 3.6 V.
